`ok &= ...` is more common in the codebase than `ok = ... && ok` when
accumulating a result while unconditionally executing functions. (`ok =
ok &&` is used in cases that should short circuit.) In this case
multiple checks may fail and their error messages may aid in debugging.
This will also improve the formatting when clang-format is applied to
the codebase.
